The second-level alchemist, alchemy at night, combined with the elixir that the two of them had recently harvested, Xuanyuan Hong felt that even if he was confused, he should have guessed what elixir Sun Hao was refining.

Without him, Tsukidaner!

Xuanyuan Hong doesn't take Zhuji Dan to heart, with her status and status, Zhuji Dan is not rare, seeing Sun Hao secretly alchemy, I think it's quite interesting, but, this Sun Hao Sun Agarwood doesn't want Qingyunmen's points? You know, Qingyunmen's points, that is, the contribution of the sect, are very useful, and many disciples have no way to ask for it.

As the two of them went deep into the Black Valley, most of the Zhuji Dan elixirs were collected, and Sun Hao opened the furnace for alchemy.

After about 20 days of entering the Black Valley, Sun Hao has unconsciously accumulated a batch of Zhuji Dan, of which there are more than 20 high-grade ones, more than 20 middle-grade ones, and there are fewer low-grade ones, only about a dozen of them.

What makes Sun Hao strange is that no matter how refined his alchemy is, he will always be unable to refine the legendary best spirit pill, Sun Hao speculates that it is likely that the best spirit pill is also the same as the best rune seal, with special refining requirements.

After refining so many Zhuji Dan in one go, Sun Hao felt that he had given the Qingmu Sect an errand, so he had to keep a part of the elixir found later and hand it over in exchange for the points of Qingyunmen, and if it was possible, he also needed to strive for a higher ranking, so that he could bring a few people to Qingyunmen to practice.

After Sun Hao stopped refining Zhuji Dan, the two began to explore the Black Valley day and night, the Black Valley covers an extremely wide area, and there is no end in sight, Sun Hao has been exploring the depths of the Black Valley with Xuanyuan Hong, looking at the deep valley, Sun Hao sometimes wonders, will his trip to the Dragon Bird Secret Realm be wandering around in this valley?

If Sun Hao didn't rush forward and searched around the Black Valley like this, he would be able to spend two months in the Black Valley without worrying about no spiritual grass harvest. However, Sun Hao thought that the Dragon Sparrow Secret Realm would not be so simple, so what is the secret of the Dragon Sparrow Secret Realm? If you want to know the answer, the way is very simple, go forward, keep moving forward, go to the depths of the Black Valley, and you will naturally find clues, unless, this Black Valley is endless.

In fact, just as Sun Hao expected, on the twenty-second day, the two came to the deepest part of the Black Valley, and what appeared in front of them was a huge ancient tree without friends.

This ancient tree soars into the sky, covering the sky and the sun, the crown covers an area of up to ten miles in diameter, up to more than 30 zhang, it looks magnificent, the compound leaves are as long as a fan, the leaf shaft is sparsely pubescent, the base of the petiole is expanded, wrapping the bud......

Under the giant tree, there is a meadow, looking from a distance, the meadow is like a small medicine garden, every other distance, there is a spiritual grass growing, among which is the extraordinary foundation building pill.

If the two of them can enter the medicine collection, there will be a good harvest.

However, this ancient tree is obviously not easy to get along with, not to mention anything else, let's just talk about the white bones at the roots of the ancient tree, as well as the animal skins hanging on the branches and leaves of the ancient tree fluttering in the wind, all of which remind Sun Hao and Xuanyuan Hong to be careful.

These things don't appear out of thin air, I think they are terrifying spectacles formed after being killed by ancient trees.

Looking at the seemingly calm ancient tree from afar, Sun Hao knew that if he wanted to know the secret of the Dragon Sparrow Secret Realm, the ancient tree must be passed, and the ancient tree was like a checkpoint, blocking the way of the two.

The two stopped and discussed for a while, and Sun Hao asked Xuanyuan Hong to take the Chaotian Aya to catch the two black jackals of the Great Perfection of Qi Refining.

According to Sun Hao's explanation, Xuanyuan Hong's distant imperial envoy Chaotian Aya threw a spirit beast towards the ancient tree with a whoosh.

The spirit beast has not yet approached the ancient tree, the branches and leaves of the ancient tree are windless and automatic, many branches like vines are entangled in the spirit beast like lightning, and many branches turn into sharp swords and pierce into the body of the spirit beast, injecting toxins, this qiē speed is extremely fast, completed in an instant, and then, without a cup of tea, the flesh and blood in the spirit beast's body have been turned into pus by the ancient tree, and the branches of the ancient tree are happily dispersed, at this time, there is only one spirit beast fur hanging on the branches. Flesh and bones are gone.

Sun Hao and Xuanyuan Hong glanced at each other, a trace of caution appeared on their faces, the Qi Refining Great Perfection Spirit Beast, they didn't even have time to snort, they were sucked up so quietly, this harmless ancient tree is probably a huge killing machine.

Sun Hao thought about it for a while, and asked Xuanyuan Hong to throw the spirit beast to the ground and untie it. Xuanyuan Hong did as he said, and after the spirit beast was unraveled, he fled in a hurry on the ground, and above the ground, countless vine spikes suddenly rose up to entangle the spirit beast, and then, the spirit beast was instantly destroyed.

Sun Hao asked Xuanyuan Hong to tie up a flying bird, and the imperial envoy Chaotian Aya flew over the ancient tree, and found that the branches of the ancient tree rushed into the sky like sharp swords, entangled in the bird, and the bird could not take off and was destroyed in an instant.

Seeing this scene, Sun Hao and Xuanyuan Hong looked at each other and smiled bitterly, this guy, in addition to not being able to move, is simply an all-round killing weapon, and there is no weak link.

The two of them observed for a while, each of them compared the information they had learned, discussed it, and finally recognized the origin of this huge ancient tree. This should be a variant of the giant tree of "hairy leaf dragon claw giant ghost locust", however, this tree has been cultivated into a demon tree, and then called it a locust tree, but it is not appropriate, the two discussed for a while, Xuanyuan Hong disliked the name of this tree was too long, because the two were in the black valley at this time, so they called this tree: "Black Mountain Old Demon".

Sun Hao has no objection.

Xuanyuan Hongti yì: "Sun Hao, this old demon of the Black Mountain is very difficult to deal with, to deal with it, we are only afraid that our current ability is insufficient, but if we want to bypass him, we have a way to think about it."

Sun Hao smiled and said, "Xiaohong, you mean to walk from the air?"

The results of the test between the two of them just now show that the control of the old demon of Montenegro in the air does not exceed 100 zhang, that is to say, as long as the two of them fly higher than 100 zhang, it is naturally not a problem to bypass this old demon of Montenegro.

However, under normal circumstances, the Qi Refining Cultivator Imperial Envoy Flying Sword could not fly as high as a hundred zhang. Xuanyuan Hong took out a shuttle-shaped instrument that I don't know if it was a magic weapon or a spiritual weapon, and said with a smile: "This is the cloud-breaking shuttle I traveled, and our two envoys have no problem flying up to 300 meters."

It seems that Xuanyuan Hong is confident, and it is no wonder that he dares to mention the words of bypassing the old demon of Montenegro.

However, Sun Hao looked at the grass under the giant tree, which was like a small medicine garden, shook his head slowly and firmly, and said: "Since the Dragon Bird Secret Realm has set up this ancient tree to block the way, I think it has its purpose of survival, if we simply bypass it, I am afraid that something will be wrong in the end", of course, in his heart, Sun Hao is still reluctant to give up the elixir everywhere.
